I was going to ask the same question but decided not to bother. Not being privy to the route planning strategy of the ME3/4/3½ or the intricacies of the NI aviation market, I cannot offer any real evidence as to if/why any route may or may not be viable either now or in the foreseeable future.
I would certainly think it's possible though and would stand by my earlier statement that I think one of these carriers will serve us at some point in the future.
